Requiring little or no sample pretreatment, ambient mass spectrometry allows the direct characterization of raw samples at molecular levels under an open atmosphere[1]. Due to the unparalleled sensitivity and specificity, ambient mass spectrometry has been increasingly considered for wide applications in food science and industry. In virtually any type of food samples could be directly analyzed using mass spectrometry powered by one of the currently available ambient ionization techniques.
Typically, trace amounts of analytes on solid foods could be rapidly detected using either desorption electrospray ionization (DESI), direct analysis in real time (DART) or desorption atmospheric pressure chemical ionization (DAPCI)[1, 2]. Both volatile and non-volatile analytes could be detected by ambient ionization techniques for surface analysis. For more consistent results, heat, solvent extraction or gas liberation would be preferably used during the desorption/ionization process for detecting analytes of low volatility, particularly on viscous food surfaces (e.g., cheese, icy meat etc.). Alternatively, liquids and gaseous samples could be real time monitored using extractive electrospray ionization (EESI) or its derivates[3, 4].
Rapidly revealing the chemical information inside bulk foods is of paramount importance in food science and industry. Herein internal extractive electrospray ionization mass spectrometry (iEESI-MS)[5] was developed to probe the molecules inside a 3-D bulk food sample requiring no mashing/grinding the sample or matrix clean-up. To date iEESI-MS has been applied to the qualitative characterization of various biological samples (tissues, fruits, vegetables, etc.) and accurate quantitative analysis of 6 β-agonists in bulk meat samples, opening new possibilities in food science and industry.
In this talk, the principle of ambient mass spectrometry, typical instrumental setup and applications would be systematically reviewed, the advantages and shortages of ambient mass spectrometry for food analysis would be mentioned, and the impact of ambient mass spectrometry on food industry would be briefly discussed.

Malt extract is a source of nutrition, energy, vitamin B and sometimes it is used as a “tonic”. The purpose of this presentation is to show the effect of using malt extract in yogurt production and evaluate the end product in terms of health.
Malt extract is a very valuable nutrient since it contains easily digestible carbohydrates like dextrin and maltose, protein decaying products, enzymes and vitamins. Malted milk is used most widely. When malt and milk are combined during the milk production process, the fat globules are encapsulated and become protective against the oxidative stress.
In recent years, because of this suitability of malt and milk, they were started to be used in ice cream and cheese industry. Malt extract-added yogurt contains water-soluble fructans, fructo-oligosaccharides and some nutrients which exist in malt contents and are considered as prebiotics. The presence of these substances in food makes it a functional food.
By adding the malt extract, the appearance, flavor, texture and taste of the yogurt was optimized. Malt extract can be used in production of yogurt and it can be acceptable and supporting in the health perspective.
Keywords: Malt extract, yogurt production, prebiotic, functional food

Background: The gastrointestinal tract is the portal for the entry of dietary nutrients, and a number of intestinal hormones such as ghrelin, glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) are involved in their absorption and storage. A direct effect on adipose tissue is highly likely if specific receptors for these peptide hormones can be identified in the tissue. While specific receptors for GIP have been reported in adipocytes, studies have been inconclusive with regard to GLP-1 and nothing is known with respect to ghrelin.
Aim: To determine: (1) if the genes for the ghrelin, GLP-1 and GIP receptors are expressed in mouse (3T3-L1) and human (Simpson-Golabi-Behmel syndrome; SGBS) adipose tissue cell culture systems; (2) at what stage of adipocyte maturation, receptors for ghrelin, GLP-1 and GIP are expressed; (3) to assess whether receptors for GIP (GIPR), GLP-1 (GLP-1R) and ghrelin (ghrelinR) are expressed in each of the major mouse adipose tissue depots.
Outline methods: Species specific primers were designed and RT-PCR was performed on RNA extracted from mouse adipose tissue depots, and 3T3-L1 and SGBS cells. Expression of the genese for GIPR, GLP-1R and ghrelinR was examined.
Results: (1) GLP-1R, GIPR and ghrelinR mRNA was detected in several tissues, including four major white adipose tissue depots in mice. (2) 3T3-L1 and human SGBS adipocyte cell culture studies show that GIPR, GLP-1R and ghrelinR genes are expressed late post-differentiation.
Conclusion: GIP, GLP-1 and ghrelin receptors are expressed in the major mouse fat depots as well as mouse and human adipocyte cell culture systems. Hormonal signals from the intestine may influence adipocyte function.

The commonly used polycarbonate bottles contain Bisphenol A (BPA). Exposure to BPA causes cancer and mimics the hormonal system in pregnant women and children. Only recently, the polycarbonate bottles are banned, in India. As an alternate to BPA, Polypropylene (PP) is used in baby bottles, drinking straws and microwavable wares. The major chemical migrants in PP namely, Octa decyl 3(3-5 di-tert-butyl-4-hydroxy phenyl) and propionate/ Iganox 1076 are known to cause cancer of liver, kidney and lungs in experimental animals. Hence the present study was conducted to synthesize a protective coating from four medicinal plants, of which Glycyrrhiza glabra was found to possess the highest antioxidant, antimicrobial and anticancer properties. The particle size, zeta potential and EDAX of nanoparticles from Glycyrrhiza glabrawere 34.7nm, -24.7mV and 2.60 percent of silver respectively. These properties along with the phytochemicals, augmented the chelating and antimicrobial potentialities of the plant extract. Thin layer chromatography of Glycyrrhiza glabra showed the presence of phenolic compounds and antioxidant activity of 520 μg. FTIR results revealed chlorohexidine salts peaks at 1157 cm-1, which indicate breaking up of lipopolysaccharide. Chlorohexidine is a cationic biocide that damages the outer membrane of gram negative bacteria. Secondly the peak 1442.72 cm-1 corresponds toC=O stretch which shows remarkable intensity changes, revealing better antimicrobial potentials of the encapsulated nanoparticle compared to the raw plant extract. The GC/MS identified the following compounds namely tetradecanoic acid, Z, Z 2,5 pentadecadiene-1-ol, cis-9,10 epoxy octadecan-1-ol, 9 octadecenal and hexadecanoic acid. Hence, Glycyrrhiza glabra nanoparticles were coated onto the feeding bottles and the foods stored in them were tested for their shelf-life for three hours. Nano coats of Glycyrrhiza glabra were also tested on pet bottles and ziplock covers and foods tested over 10 days. Milk stored in feeding bottles recorded a maximum microbial inhibition of 84 percentage and diluted lemon juice showed no microbial growth of S.dysenteriae. On 10th day, nanocoated zip lock covers and PET bottles showed a maximum microbial inhibition of 38, 63 and 83 percent and 57, 68 and 88 percentage against E.coli(MTCC 40), S.enterica (MTCC 3219) and S.dysenteriae (PSGIMS & R) respectively. The MTT assay of Glycyrrhiza glabra nanoparticles showed a maximum apoptosis of 50 and 48 percent against Hela and liver carcinoma cell lines respectively. The gel electrophoresis has led to a longer tail DNA damages with the Hela and carcinoma cell lines, compared to the control and marker. Therefore, nanocoats of Glycyrrhiza glabra could be used for effective protection against oxidative damage, diarrhea and cancer.

The taxifolin (TXF) is recently rediscovered as a highly potential antioxidant with reported therapeutic properties. However, the data about possible protective properties of TXF and information about its stability is scarcein meat sausages. The aim of this work was to evaluate the antioxidant and antimicrobial activity of TXF when it is used together with ascorbic acid (AA), linalool, dipeptide carnosine(CAR), lactic acid (LA) and their mixtures indry-cured pork sausages during storage. Also, possible biochemical interactions among these bioactive substances on cell apoptosis and proliferation-related variables in the human cervical cancer HeLa cellshave been investigated. The activity of tested materials against lipid and protein oxidation, the grower of microorganisms and stability of TXF has been evaluated in dry-cured sausages after 0, 30, 60, 90 and 150 days of storage. The evaluation of TXF stability has been performed by UHPLC analysis. On the 150 day of storage the total amount of TXF was higher in sausages with TXF+LA (40% less) and with TXF+AA (54% less), comparingwith the 1st day of storage. Meanwhile, the retained amount of TXF in the samples without acids was 60% less, comparing with the initial amount. TXF antioxidant capacity (DPPH) was higher in the samples with LA or AA and effectively inhibited the processes of lipid peroxidation as well as slowed down the rate of lipolysis. Moreover, TXF mixtures with acids reduced the number of total aerobic bacteria, mold and yeast during storage of sausages. The treatment of combination of the three compounds (TXF, CAR and AA or LA) on HeLa cells (by MTT method) resulted in a significantly lower percentage of live cells number than treatmentonly with individual substances in different concentrations (P<0.05). The outcome of this study can help develop new meat products with better nutritional quality and beneficial health properties.

Introduction: Diabetes mellitus comprises a group of metabolic disorders that share the feature of hyperglycaemia. It is worldwide in distribution and the incidence of both type 1 and type 2 diabetes is rising dramatically. Globally, diabetes is one of the most common non-communicable diseases leading to mortally and morbidity in many developed countries. The increased risk has been attributed to the high prevalence of multiple atherosclerotic risk factors among diabetic patients. Cardiovascular disease is increased in individuals with type 1 or type 2 DM. In patients with Type-2 DM, cardiovascular disease (CVD) is the major cause of morbidity and mortality. In fact, diabetes is considered as a coronary equivalent, approximately 80% of all deaths and more than 75% of all hospitalization in patients with diabetes is due to CVD.
Objective: To find out the association of dietary pattern and CVD risk factors, among recently diagnosed as Pre-diabetes subjects.
Methodology: This is a hospital based cross-sectional and case-control study with newly diagnose Pre-diabetes, aged 20-50yrs, of both sexes. Out of 50 subjects screened only 16 subjects were recruited as pre diabetes based on their HbA1c values (DCCT-5.7 to 6.5%) from the outpatient Department of Osmania General Hospital Hyderabad, India The various biochemical parameters viz Fasting blood glucose, HbA1c (glycated Hb) Lipid profile, i.e., Total Cholesterol, and Triglycerides LDL, VLDL and HD Lcholesterol were analyzed using commercially available kits.
Results: Our results indicate that there were significant changes in the values of Fasting blood glucose, Total cholesterol, Triglycerides etc upon probiotic supplementation for a period of 30 days in the Pre-Diabetes subjects compared to non supplemented control group.
Conclusions: From this study we could conclude that the probiotic curd supplementation may prevent the progression of pre diabetic mellitus over to diabetes mellitus.

The quality of commercial virgin olive oils is guaranteed by chemical and organoleptic (Panel Test, PT) analyses.
The aim of this research was to transform VOCs perceived by the human olfactory sense in a meaningful spectra profile useful to distinguish oil trade classes (EVOO/ Not EVOO), and to grade EVOO, based on the intensity of the main positive (fruity) attribute using a fast and not expensive VOCs test, also useful to promote at consumerʼs level the sense of quality by smell and lack of defective odors.
Extensive surveys were carried out on 150 olive oil samples from different countries, processed as monocultivar or blend, acquired to producers or in the stores. Samples were analyzed by a PTR-ToF-MS as its high resolution coupled to a rapid screening power of samples, easy to handle and without any manipulation, while a PT recognized as EVOO 68/150 samples, characterized by different “fruity” flavor intensity.
A principal component analysis (PCA) of the whole PTR-ToF-MS data clustered the samples in two main groups, including the 68 samples classified by the PT as EVOO, without any defective odor, and the 82 classified as not EVOO, respectively, with only a few partially overlapped.
A PLS-DA model correctly classified EVOO/Not EVOO spectra as resulted by PT, confirming the high confidence level (95%) in utilizing analytical spectral data in helping PT.
A Fuzzy Clustering applied to the spectral data confirmed the 3 group of EVOO recognized by the Panelists, allowing to grade the samples by “fruity intensity” (1-3 = light, 4-6 = medium, 7-9 = intense).
In conclusion, throughout adequate DB the high quality of each oil sample can be predicted in any step of commercial chain of virgin olive oils processing, by a rapid and convenient way, so to define and preserve the high quality products.

Small millets have both preventive and curative properties good for addressing constipation, heart problems and type 2 diabetes suitable for preventing obesity. Small millets include, finger millet (Eleusinecoracana), Kodo millet (Paspalumscrobiculatum), little millet (Panicumsumatrense), foxtail millet (Setaria italic), proso millet (Panicummiliaceum), and barnyard millet (Echinochloacolona) and each one of them has special nutritional benefits. Small millets, perform well in marginal environments having superior nutritional properties, including high micronutrient and dietary fibre content, and low glycemic index. Despite their superior nutritional qualities and climate resilience, cultivation of small millets in India declined from 7.22 million hectares to 2.29 million hectares between 1961 and 2009, this decline in production and consumption of small millets mainly due to limited productivity, high drudgery involved in their processing, negative perceptions as a food for the poor. Through context-specific production technologies, creating decentralized processing infrastructure and local market development it is possible to bring back small millets to farms and food baskets on a wider scale. Among the children under the age of five years in India, 48 percent have stunted growth and 43 percent are underweight, likewise chronic and non-communicable diseases like Type-II diabetes and impaired glucose tolerance are on the increase. The primary factors responsible for the steep decline in the production and consumption of small millets in India are; Low productivity, high labour intensity, drudgery of agricultural operations and lack of attractive farm gate prices. Promoting small millets as cropping systems, support for timely availability of quality seed, Large scale capacity building to farmers on location specific improved production practices, creating post-harvest infrastructure and marketing initiatives are some of the strategies for enhancing production. Besides, therapeutic products targeting elites need intensive efforts for quality maintenance, consumption promotion through public support and supplying ready to cook small millet products will promote small millets in the baskets of urban elites are discussed in this paper.

Mungbean is the third most important pulse crop in India. Among the fungal diseases, powdery mildew, anthracnose, Cercospora, web blight and dry root rot are the most prevalent. Apart from diseases some fungi are also causing qualitative and quantitative loss in storage. The study was conducted to know the seed mycoflora associated with mungbean and their management. Seeds samples collected from different districts were plated on moist blotters. Twelve fungi belonging to ten genera viz., Aspergillus niger, Alternaria alternata, Aspergillus flavus, A. candidus, Penicillium notatum, Rhizopus stolonifer, Cladosporiumsp., Fusarium oxysporum, Mucorsp., Curvularia lunata, Macrophomina phaseolina and Chaetomiumglobosum were observed from seed samples. Management of seed mycoflora was studied by different seed treatment methods viz., physical, chemical and biological methods. Seeds treated with hot water at 45 °C for 30 min and 50 °C for 20, 25 and 30 min reduced seed mycoflora. Seed treatment with dry heat treatment at 50 °C for one hour effectively reduced the seed mycoflora. Seed exposed to solar heat treatment between 12-2 pm effectively reduced the seed mycoflora. Seed treatment with captan recorded the maximum inhibition of seed mycoflora (78.68%) followed by carbendazim (68.30 %), thiram (65.57 %), chlorotholonil (62.29 %) and vitavax power (62.84 %) at the rate of 4 g kg-1 of seed. T. harzianumseed treatment at the rate of 8 g kg-1 of seed inhibited seed mycoflora up to 69.63 per cent followed by P. fluorescens (66.49 %), T. viride (64.39 %) and B. subtilis (63.79 %).

Dates (Phoenixdactylifera(L.) are extensively produced and consumed in Middle East. Dates flesh is consumed as a food while pits are thrown as waste or used as animal feed. Date pits comprise of 10-15% of total fruit weight. Date pits are rich source of dietary fiber (52%). Pits can be used in different types of food products to improve their dietary fiber contents. Bread loaves were prepared with acceptable sensory and rheological dough properties when date pits powder was replaced with wheat flour up to 12% level. The pasting properties of flour blends were also affected in the presence of date pits. Date pits pudding was also prepared and compared with commercially available chocolate pudding. Acceptable sensory and rheological attributes were observed in high fiber date pits pudding samples. Hardness and spread factor of cookies also increased in the presence of date pits powder. It can be concluded that date pits can be used as a cheap source of dietary fiber in different products without promising their quality attributes. The presence of good quality oil in date seed powder can also enhance the nutritional value of these food products.

Rain induced fruit cracking is an important problem in sweet cherry industry, causing loss up the 90%. Recent studies have suggested that a primary cause of fruit cracking could be the increase in fruit surface area during fruit development in the absence of deposition of cuticle membrane (CM) deposition. Abscisic Acid (ABA) and Methyl Jasmonate (MeJA) are phytohormones associated with stress tolerance, cuticle wax biosynthesis and fruit ripening. The objective of this research was to evaluate the effects of exogenous ABA plus MeJA applications on several quality parameters of sweet cherry fruits (cv. Bing). The application of theses hormones at different fruit development stages increased differentially the fruit cracking tolerance and fruit color at the ripening stage, affecting the soluble solids content, malic acid concentration and fruit cuticle resistance.

The effect of processing on the quality properties of cassava and its starch was reviewed. Cassava (Manihot esculenta Crantz) is a broadly cultivated root crop and mostly consumed in developing nations. Cassava can be processed into flour, chips and starch for subsequent use in food production. Fermentation, boiling, drying, steaming, baking, blanching, frying and parboiling are some of the methods of processing cassava roots. These processes lead to a reduction in its cyanide content and other effects on cassava quality. The use of native cassava starch in food industry applications cannot be over emphasized; however, a major factor militating against its use is the finite imbalance in its structure and properties. As a result of this, native starch from cassava requires some form of modification to enhance its quality in terms of structure and functionality.

Campylobacter is a gram-negative bacteria with at least 16 different species which some of these species are important in foodborne disease in human. Campylobacter is the most important cause of human bacterial gastroenteritis particularly in developed countries. Campylobacter coli (C. coli) and C. jejuni are the two most common species that are reported from enteric infections in Australia and usually are associated with poultry meat as contamination of carcasses may occur at processing plants. In this study, a rapid molecular diagnostic and genotyping method was developed to detect and differentiate C. coli and C. jejuni in broilers carcasses. The test was evaluated further by investigating additional human samples. The sensitivity and specificity of the test was 100% and 92%, respectively.
Keywords: Campylobacter, genotyping, poultry meat

CentaureakarduchorumBoiss. Belonged to the Asteraceae (Compositae) which is represented by 1100 genera and about 25000 species in the world. It has a total 1209 species in the flora of Turkey. Interms of the number of species, Asteracea family is the richest family in our country. The genetic origin of Centaurea genus is turkey which this genus is quite common. This plantused as digestion, diuretic, antipyretic, antidiabetic, anti-inflammatory and antibacterial. Centaureakarduchorum Boiss species spread naturally in the Van lake in the Eastern Anatolia Region of Turkey and is a perennial endemic species. The leaves of are consumed as herbal tea by the local people for the treatment of diabetes.
In this study, the nutritional values and mineral compositions of CentaureakarduchorumBoiss which grown as wildplants in Van region of Eastern Anatolia, Turkey were examined. The chemical character sestimated included as N, Na, Mg, K, Ca, P, S, Mn, Fe, Cu, Zn, Cr, Cd, Co as well as total ash, crude protein, crude fiber and pH.
A result of research, the ash content was obtained as 5.93 %, nitrogen content 1.75 %, crude protein content 10.93 %, pH 6.66 and crude fiber 32.58 %. Also, the detected values were as follow: Potassium content 5.57 g/ phosphorus 1.18 g/kg, magnesium 5.71 g/kg, sulphur 1.12 g/kg, manganese 79.56 mg/kg, zinc 15.18 mg/kg ve iron 583.56 mg/kg.

In this study, the aim is to determine the storage condition of Ziraat 900 sweet cherry cultivar in province of Mersin in Turkey and to find out the effectiveness of treating the UV-C, Hot Water and the combination of both in protecting the fruit quality during storage in MAP (modified atmosphere packaging). For this aim, clusters of control group were not subjected to any application in the postharvest period, while clusters of treatment group were performed with VilberLourmat UV-C lamp glimmered 254 nm wavelength from 100 (0.25 kJ / m2) cm distance for 4 minutes in the sterile cabinet without any fumigation. Hot water application was also performed by maintaining of clusters in the water bath at 50 °C for 1 minutes. After treatment, by covering of all clusters (in the control and treatment groups) with stretch film with packing containers called modified atmosphere packaging, all clusters were stored at 0 ± 1 °C and 90 ± 5% relative humidity conditions in the cold storage room. For this purpose, cherry fruits was kept for 20 days in 0°C cold storage. Weight loss and color (L*, a*, b*, Chroma, and Hue), SSC (soluble solid content), titratable acidity, pH, total phenolics and total antioxidant changes that occurred postharvest storage were examined. As a result of this study, an increase in weight loss was detected during storage in all applications. As a result of study, it was concluded that cluster of Ziraat 900 sweet cherry cultivars subjected to hot water and UV-C can be stored for optimal 20 days by covering with stretch film.
